That never materialized. Third-year player Pryor beat out Flynn by the end of training camp, and he solidified his standing with impressive play in his first three starts combined with a disastrous outing by Flynn in relief of an injured Pryor against the Washington Redskins.

"This kid's going to continue to improve," Allen said of Pryor. "He's probably leaps and bounds ahead of where we thought he would be at this point in time. The key for him is he continues to work and continues to strive to get better on the little things."

Undrafted free agent Matt McGloin is the only other quarterback on the Raiders 53-man roster. Allen said it's conceivable that the Raiders will promote Tyler Wilson from the practice squad.

Also, the Raiders worked out veteran David Carr on Monday, so it's possible that they will sign him for his veteran presence.

McKenzie restructured Flynn's contract soon after he consummated the trade with the Seattle Seahawks. The new deal called for Flynn to receive $6.5 million guaranteed this season.

The Raiders agreed to give the Seahawks a fifth-round draft pick in 2014 and an unconditional selection in the 2015 NFL draft. Overall, Flynn earned $14.5 million the past two seasons, even though he got beat out for starting jobs with the Seahawks and Raiders.

Flynn was unavailable for comment.

The Raiders activated wide receiver Andre Holmes from the suspended list and placed him on their 53-man roster. Holmes filled the vacancy created by the release of Flynn.

Holmes was suspended the first four regular-season games for his violation of the league's policy on performance-enhancing substances.
